Comparison Study on SS and Double-Sided LCC Compensation Topologies for EV/PHEV Wireless Chargers

Abstract: This paper compares the characteristics of the series-series (SS) and double-sided LCC compensation topologies for electric vehicle (EV) wireless chargers. Both the well-tuned and mistuned topologies for the two compensation methods are analyzed in detail. The mistuning considered here is mainly caused by the variations of the relative position between primary and secondary sides. The output power displacements (PD) caused by mistuning are compared for both compensation topologies, as well as the impacts of th… Show more

“…A perfect T-type network is not the best solution at the primary side to achieve these goals because the equivalent load of the inverter must be somewhat inductive to achieve ZVS. Certain variations [26,28] of the LCC network are needed. One previous work [26] proposed a method that added coefficients α and β to the left and right sides, respectively.…”

“…Among them, the compensation circuit is essential because it can be used to tune the resonant frequency of the system, reduce the reactive power in the power electronics converter, and improve the transferred power capability and efficiency [4,6]. According to the way in which the compensation capacitors are connected to the primary and secondary coils in the compensation networks, the basic compensation topologies can be classified into four types, that is, series-series (SS), series-parallel (SP), parallel-series (PS) and parallel-parallel (PP) [6,7]. A detailed analysis of these four basic compensation topologies has been conducted in [8,9].…”

“…However, the SP compensation circuit is easily mistuned because the primary compensated capacitance relates to the coupling coefficient [10], which means the resonant frequency is dependent on the coupling coefficient. Therefore, SS compensation topology is superior to the other three compensation topologies because its resonant frequency is independent of the coupling coefficient and the load conditions [6]. The defect of the SS compensation topology is the poor output voltage regulation capability [11], so many other compensation topologies have been proposed in order to improve the efficiency or Energies 2018, 11, 307 2 of 14 realize other purposes [12].…”
